Review: Indus Civilization


Explanation

Creating a filter: in the sentence as written, the first thing we notice is that the word "that" is missing: "such severity that they." Our ear tells us this and "such... that" is a prior idiom.

Applying the filter: choices (B) through (D) fix the problem in the way we expect. (C) has an unnecessary pronoun with no reference in "this," and (D) has an unnecessary gerund "being." Both (C) and (D) also have basic errors in connecting clauses with conjunctions: (C) throws one into the middle of the sentence as if it were an appositive, which it isn't, and (D) inserts a comma without adding or re-mentioning the subject. Choice (E) is missing the word "that" and includes the gerund "being" without cause. The correct answer is (B).
